'McElroy, Kansas City, Application December 29, 19 3 7, Serial No. 182,326 10 Claims. (01. 56-403) This invention relates to a combination grain binder and shocker, the present application be-,

mg a substitute in part for an "application filed by me on November 12, 1925, Serial No. 68,58Q. 1

The principal object of the invention is to'provide an inexpensive, durable, and efiicient combination grain binder and shocker to cut grain, bind the grain into sheaves, form the sheavesinto shocks, and deposit the shocks upon theground with the heads of the grain upstanding so that the shocks may be subsequently gathered for threshing.

Other objects of the invention are to provide means for tyingthe shocksv before depositing them on the ground; to provide means for dropping one or more sheaves to the ground for. use as caps; to provide means on the binder to de tain sheaves while the shocker is depositing a formed shock; and to provide meansfor' control ling tension on the twine with which the shock is tied.

In accomplishing these and other objects of the invention, as hereinafter described, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

' Referring more in detail to the drawings:

The graincutting and binding portion of the machine is of conventional construction and may bebriefiy describedas including 'a grain platform I carried'by a main wheel I68 and a grain wheel 20 H0. Supported on the front of the platform is a sickle 3 forcutting thegrain which is transferred by a conveyor 2 to an inclinedbinder deck 5 which is supported over the main wheel and carries the sheaf forming and tying mechanism, 26 later described. The main wheel I68 is carried in standards l84and [B ion the binder frame I86 and cooperates with the grain wheel in supporting the platform. Thebinder also includes the usual re'el, operators'seat and platform tilting lever, 80 the operators seat being carried .on the goosenecksl ppdrt llfi. The bundle carrier of a vconventional binder and its associated parts, however, are eliminated and substituted by the shocker mechanism as later described. The conveyor 2 is of the ordinary ,slat and canvas type carried by side chains I44 and M5 which maneuver sprockets l4'| 'l 48 idling upon a shaft I45 carried at'the grainward end of the platform, the sprockets being retained in spaced position by kys" g and 149' as shown in Fig. 14. The opposite ends of the chains operate over'sprockets I and T56 fixed to a shaftl59 supported by the harvester frame adjacent the upper portion of thbinde'r deck 5. The section of the conveyor operating over the platform is retained in horizontalposition by guide plates l50--|5l-a'n'd rollers [52- 453 lcarriedby the front and rear sills of the platform, the rollers-being retained] in suitable-bearings by spring c'otters 154 as shown 50 inFig. 14. 'From therollers l52 and l53-the conveyorxinclines'yupwardly'todischarge the grain ontothe binder' 'deck with the aid of a roller 6. Cooprating'withthe inclined portion of the con veyorlisan upper' conveyor 4 driven from a gear 55? sheaves which are discharged I79 meshing with a gear I51 on the shaft I59. The roller 6 is also driven from the gear I51 by a gear I58 meshing therewith and fixed to the roller shaft 6 as shown in Fig. 14. The reel of the binder is also driven from the shaft I59 through miter-gears I86 and I8I which are connected with the customary reel operating connections (not shown).

The shaft I59 is driven by an endless chain I60 (Fig. 1) operating over a sprocket I88 on the rear end of the shaft I59, a sprocket I8'I' for operating the tying mechanism, over a driving sprocket I6I which is fixed to a pitman shaft 35 journalled in the frame I86, and over a tightening sprocket I62 as shown in Fig. 1. Fixed to the pitman shaft is a miter-gear I83, meshing with a miter-gear I81 on a counter-shaft I64 which is driven from a sprocket I63 on the main wheel I68, through a chain I66. It is thus 'obvious that the platform conveyor, upper conveyor 4, reel, sheaf forming mechanism, and roller. 6 are all driven from the main wheel incidental'to movement of the machine along the field;

The pitman shaft 35 carries apitman wheel 35 to operate the sickle 3 through a pitman 3'.

The grain delivered to the binder deck gravitates onto packers 1 cooperating with a'butterboard 8 to convey the grain against compressor springs IIJ, 'II and II and a trip 9 which sets the tying mechanism into action to tie the grain into I by arms I2 into the shocker mechanism.

The shocker includes a frame rigidly attached to the binder frame I86 and includes side bars I5, I6, I'I, I8and I9, a front cross bar 20, a rear crossbar 2i and upright bars 23, 45, 4'6 and 85. The shocker includes an upender I3 and a butt holder I4. The shock upender isof substantially U-shape, carriedby a substantially U-shaped shaft-like member 25 having lateral ends 26 and 21 rotatable in suitable bearings on the'frame bars I5 and I6 respectively. The shaft end 21 projects through its bearing on the bar I6 and 'end to the shock settler as at M has itsfree'end mounted in a bearing on the bar I1 which is connected to the bar l6 by 'the'bar I9 as shown in Fig. 17. .The upender also includes a shock settler36 that is connected to the top of the upender at 3] and 38 and at the bottom by a spring 39, the. spring 39being connected at one end to the upender as at 40, and at its other The butt holder I4 is carried on a shaft'42 at the front end of the shocker frame and journalled in'bars' and 46. which depend fromthe front cross bar 28, the shaft 42 having-rearwardly extending arms 43'an'd supporting the butt holder I4. Hinged to the crank-arm 44 is a link 41 hinged at its upper end w a lever 49 which is pivotally mounted on the bar I5 as at 50. Connected with the lever'49 is a'chain 5| having its other end'c onnec ted to a double acting crankx trip stop lever 55,;adaptedeto retainthe shock arm 53,as at 54, the crank-arm 53 being pivotally attached toacrank-arm 59 on the shaft end 26 to, thus connect the upender with the butt holder. Hinged onv the side bar I5, as at 56, is a holder home when a shockis being formed. I The trip stop 55 has a retracting spring 51 (Fig. 4),. fastened at one end tothe trip stop lever and at the other to the bar-15.1 The crank-arm 53 hingesvon'e'way about the center ofthe crank- 1 arm 59: andengages under the stop lever to support the upender and butt holder in position to swings to drop the butt of a shock to the ground and the upender is free to turn and cooperate with forward travel of the machine in upending a formed shock. While the upender is making about the first quarter turn, or when the shock is onend, a fast speed mechanism automatically comes into play and speeds up the upender so that the upender is rotated at a fast speed to clear the upended shock. This mechanism in cludes a bevelled gear 28 and an interconnected clutchwheel 29 loosely mounted on the end 21 of the shaft 25 (Fig. 7). The bevelled gear 28 is rotated by an intermeshing bevelled gear 30 on a shaft 3-I journalled in suitable bearings attached to the bar I9 and which is driven by a sprocket 32 fixed on the shaft and actuated from .a sprocket34 on the pitman shaft 35 by an endless chain 33 operating over the respective sprockets.

Cooperating with the clutch wheel is an arm 58 fixed to the shaft end 21 and hinged thereto, as

at 64, is a trip dog 63, having a toe 63' adapted to' wheel. The toe of the trip dog is normally urged toward engagement with the teeth of the wheel 29'by a spring 58 fastened to the toe of the trip dogfand to the arm- 58. The trip dog, however, is keptfrom engagement with the teeth until the upender has set the shock upon the ground, since the tail portion 65 of the trip dog rides upon an arcuate track fixed to the bar I9.

In order to control the point where the tail of the trip dog rides off the track to make the fast speed drive effective, the track preferably includes a section 69 having a lateral arm 62 pivotally connected as at 66" with a bracket 6| sewired to the bar I6 as at 6|. The arm 62 is engaged by..a roller 69 carried on a crank-arm 68 having ashaft portion journalled in bearings 61 fixed to a depending arm 22 of the rear cross bar 2 I and which terminates in a laterally extending fin'geri 66' adapted to be engaged by a deposited shock toswing the section of the track 68 out I of. engagement with the tall of the trip dog 63,

at which time the spring 58 draws the toe 63 into. clutching engagement with the teeth of the wheel29, whereupon the shaft-25 is driven at the speed of the clutch wheel to accelerate movement of the upender so that the upender gets away i 69'. whereby the effective length of the arm may be varied so that the finger 66 may be caused to trip sooner or later. The arm 68 is retained in retractive position with respect to the lever 62 by a spring I8 connecting the arm 68 with the bar I8 and the track extension 60 is normally retained in registry with the fixed track section by a spring I0 which connects the arm. 62 and. the bar l6. i Y

Mounted on the shocker frame is a tier attachment by which a string is tied around a shock prior to deposit of the shock on the ground (see Figs. 1, 2, 3, 9, 10 and 15). The tier attachment includes an oscillatory needle shaft I60 extending along the side bar I5 of the shocker frame and having its forward end mounted in a bearing IIlI' carried on the bar Zfl-and at its rear end in'a bracket I82. The needle shaft has a crank-arm IOI at its forward end and a needle I82 at its rear end.. Carriedon the free end of the needle is a twine guide and a twine hold-down; I,,03.-;to, hold thegtwine improper poslt o rzvv v Wins saleec: shock. The-twine; H2 is carried in a, container I04 .attached to the bar 46 and; extends from j the ;contai ner through; va tensionmechanism J08 (seeFig,,13),, attachedto the side. bar. I5. l Thev tension mechanism I06 includes a tension member I I3.having an arm I01 pivoted thereto as at.

The-roller I08 is adapted to be retained in tensioning position with respect .to thefpart I I3 "at predetermined times 'by a springfI I0 on a tensioning bolt I09 whereby the springis adjusted to put the proper tension onthe twine when need ed:

In order to selectively release 'ten'sion on' the twine, the lever I0! is connectedbyaspring II with a finger II4 fixed totheneedle shaft I00 so that tension onthe twine is released when the shaft moves in one direction and' is" established 4 when the needle shaft moves inlthe oppo'site direction. From the tension mechanism-the twine extends through a take-up I I5 'to the hold-down I03 and through the needle. eyes H6 and-I I'Iinto the twine disk.82'.: :fIheiknotter shaftIfII (see Figs. 6, 9 and 10), is'parallel with the needle shaft on the opposite side of the shocker frame and the front endtis mountedina bearing on the upper end of the bar 45 and the opposite end thereof is mounted. on theupright end of a= .bar fastened to the center of the bar I9 and at its lower end to the binder frame I06. vThe knotter shaft 1 Ihas a crank-arm I2 and a knotter head IS on the other end, the shaft'being rotated by'a chain I4 I operating .over a sprocket I3 on the shaft which is adapted to be connected therewith by a clutch 'I4.' Cooperating with the clutch isa trip dog 15 which hinges on a trip dog casting 93 (Fig; 8),the casting 93 being fastened" solidlyon the knotter shaft" H. The trip dog I5 has a roller 94 and a push spring '95 which works between'the trip dog' I5 'andthe trip dogcasting93 to lock the roller'94 into the clutch teeth 96 of the clutch (Figs. 9 and'10'). The crank-arm I2 is connected'to the needle shaft crank-arm I01. bya link 91. Theitrip dog stop illustrated in. Figs.w9 and-:10 consistswofja trip stop member. 98 to which isattached trip stops 8], 88 and 88.

Pivoted on a support M is ma'nually actuated trip stop 89 having a crank-arm 89 that isconnected with a cable 99 leading to the operators seat on the binder'so that the cable may be operated to trip the dog I5 to tie a shock whenever desired. Whenthe'trip stop 89 is tripped, the dog 15' contacts the automatic trip stop 98 and on discharging the next bundle it is automatically tripped to tie the 1 shock; -The trip dog stop member 98 is rocked automatically each time a sheaf is discharged from the binder.

The knotter. head includes a frame I38 journalling the shaft'II. Fixed to the'sh'aft II is a :tier'wheel 54. The knotter'head also includes the usualdisk 82, pinion I39, and knotter hook 86, Working inconjunction with the knotter head is a stripper arm I33" having a knife 8I fastened thereto 'to"cut"'the twine and strip it from the knotter hook after the shock has been tied. The breast :plate Tl'bolts on the knotter frame I38 as at I31 and I31. .boltsto the under side of the binder deck as at The top end of the breast plate 11 I40 and I40. The double acting stripper arm I33-hinges on the breast plate 11, as at 19. The

tier wheel 84 has an arm I8 and the stripper arm has a bracket wing I33 to which is connected a cable I34- as at I31"; This cable extends through The crank-arm 43 so that the stripper arm is actuated when the butt holder is tripped.

In order to prevent discharge of sheaves from Theupender trip 55 is released by a cable I28 .which-issecured to the trip, stop 55 and extends through a pulleyl30 and is connected with the .crank-arm I2, the pulley I30 being attached so the binder during operation of the shock tying and "setting mechanism, the binder discharge includes a' shaft I94 supported over the discharge of the deck 5 and which has a plurality ofhooklike fingers I93 adapted to move into position for s The shaft I94 is operated by a lateral arm I9I thereon having a finger I92 engaged in a slot at the end of a link I90, having its opposite end attached to the crank IOI of the needle'shaft. The arm I9I has a lateral extension IflB which is adapted to be engaged by an arm I on the discharge shaft to efiect raising o-f the fingers I93;and allow continued discharge of sheaves into the shocker afterthe shocker 'hasreturned-tO" its receiving position. I have also provided means for stopping return movement of 'the'upender so that one or more sheaves may be-discharged from thebinder directly onto the ground. This is effected by. a stop pin 21' which: moves through the breast plate 11 and hasa retracting spring 71'. The spring 11' has ailink 9' connected to thebinder trip 9 so that ,the pin is adapted tobe retracted after one or two bundles-have been discharged (see Fig. 16). The butt holder may also be provided with a pan I43 to prevent slipping forward of the sheaves: in the shocker while the harvester is crossing ditches, 4 1 1 While Ihave described the mechanism of the machine as driven from the main-wheel, it is obvious that the binder and shocker mechanisms shaft :I93 telescoping in a tubular shaft I92 vthat is connected by a universaljoint I9I whichmay be connected with the shaft3l (Fig.' 6)

A machine constructed andassembled asdescribed operates as follows:

The machine is connected with a suitable draft vehicle and drawn over the field, the various mechanisms being driven responsive to rotation of the main Wheel or by a flexible shaft'connection with the power take-off. The grain cut by the sickle falls onto the conveyor and-is carried thereby to the binder deck5 and is tied'in sheaves in conventional manner, with the sheaves being discharged into theshocker so that the 'heads fall into the upender and the butts upon the holder l4. At the time the first sheaf is discharged the knotter trip dog I5 engages against the .trip stop .81 .and the upender and butt holder are held home by the trip stop 55 latchingly engaging the arm 53 as shown in Fig. 2. With the trip dog 15 engaging the stop 81, the'needle shaft I is held in position so that the spring .I II is actingto relieve tension of the'roller I08 on the twine H2, which twine is connected with the knotter hook and supported by the needle over the top of the shock upender as shown in Fig. 2. Consequently, the first sheaf strikes the twine and carries it into the shocker. When the next sheaf is discharged from the binder deck, the crank-arm H9 is pulling on the link H8 to trip the stop member 98 so that the stop 81 thereon is moved away from the trip dog I thus allowing the clutch to engage and move the trip dog into stopping relation with the stop 88. Since the stop member 98 has been returned to its original position, and as the link 91 holds the needle shaft in position to exert pull on the spring III, there is no tension on the twine I I2.

When the second bundle is discharged, motion is again imparted to the link II8 by the crankarm H9 to again trip the stop member 98 and shift the stop 88 away from the trip dog 15 so that the trip dog then moves against the stop 89, thus shifting the needle shaft further to the right (Fig. so as to relieve pull on the spring III and establish tension on the twine. The tension will then remain on the twine during the completionof the shock and during tying thereof. When succeeding sheaves are deposited "in the shocker, the trip stop 88 will be actuated, but at these times the trip dog is contacting the stop 89 and therefore the trip dog retains its position. -When a sufficient number of sheaves have been deposited in the shocker "theoperator will pull the cable 99 to the shift stop 89 from engagement with the trip dog-.'|5, whereupon the trip dog is again momentarily released to engage the trip stop 88'. When the last bundle is discharged into the shocker, the stop '88 is shifted from engagement with the trip dogwith the result that the clutch begins to rotate to start the tying operation.

When the tying operation starts, the needle I02 carries the string around the shock with the twine hold-down I03 retaining the string in proper position for tying and stripping of the knot from the knotter hook. Simultaneously with the actuation of the needle, the compressor I 21 comes into play to compress the sheaves. As the needle starts back after the shock is tied, the crank-arm I2 pullson the cable I28 unlatching the trip stop I55 from the double acting crank 53, letting the butt holder I4 drop the butt of the shock to the ground. When the butt-holder I4 drops the shock to -the ground,'the butt holder crank 43 gives the stripper arm I33 another swing through the cable connection I 34 so that in case the twine has been held by the knotter hook, the extra swing will strip it therefrom. When the needle shaft I 00 is actuated to move the needle downwardly, the link I90, which is that the shock is moved to perpendicular position. When the finger 66 contacts the shock,

the roller 69 moves the section 60' of the track out of position, consequently the spring 58 comes into=play to move the toe 63'of the dog 63 into contact with the teeth of the clutch wheel at the time the end of the dog engages with the track. The clutch wheel is then effective to complete rotation of the upender and swing it quickly across the top of the shock so that it gets away therefrom simultaneously with forward movement of the machine. As the upender moves across its uppermost dead center position, the end 65 of the dog 63 again engages the track 60 to disconnect the high speed drive and the upender settles to its normal position. The change connection 5| simultaneously raises the butt holder I4, and the double acting crank is again latched by the trip 55. By the time another sheaf is formedand tied, the arm I95 engages the extension I06 on the arm I9I to raise the .hook-likefingers I93 and allow discharge of the succeeding sheaves into the shocker. In case it is desired to .drop one or two bundles on the ground for caps, thestop pinZ'I, which acts through the breast plate 11, is contacted by the shock upender, and the upender is held thereby until the binder has discharged one or two bundles from the binder. These bundles fall on :the ground, afterwhic'h the binder trip 9, through the 'link 9, releases the pin 21' from the shock upender, whereupon the shock upender returns to its original position ready to receive sheaves forforming another shock.

As above described, tension is off of the twine whenfithe trip dog 15 is engaging the stops 81 and 88, and isput on the twine when the dog is .engaging the stops 89-and 88', but attention is directed-to the fact that the tension on the twine may be removed for a greater number of bundles by the provision of more stops between the stops .81 and 89.
